The adapter sleeve is essential when replacing or servicing the clutch drum assembly. In large classic saws like the 070 and 090, the drive sprocket is a separate component, and the adapter sleeve ensures correct mounting of the clutch drum to the crankshaft for smooth power transmission .
Drive System Overhaul & Maintenance
When the chainsaw exhibits reduced cutting performance, chain slippage, or excessive wear on drive teeth, the adapter sleeve should be inspected during drive system overhaul. Replacing a worn sleeve along with the clutch drum and sprocket ensures all components are renewed and properly aligned .

For vintage 070, 090, and Contra series saws being restored to factory condition, the OEM-spec adapter sleeve (1106 162 9000) is a critical component for maintaining correct clutch alignment and preserving original equipment specifications .
